Emerging roles of telomeric chromatin alterations in cancer [PDF]
, 2019 Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...

Regulation of Gene Expression through Food—Curcumin as a Sirtuin Activity Modulator
Plants, 2022 The sirtuin family comprises NAD+-dependent protein lysine deacylases, mammalian sirtuins being either nuclear (SIRT1, SIRT2, SIRT6, and SIRT7), mitochondrial (SIRT3, SIRT4, and SIRT5) or cytosolic enzymes (SIRT2 and SIRT5).

A small molecule ApoE4-targeted therapeutic candidate that normalizes sirtuin 1 levels and improves cognition in an Alzheimer's disease mouse model. [PDF]
, 2018 We describe here the results from the testing of a small molecule first-in-class apolipoprotein E4 (ApoE4)-targeted sirtuin1 (SirT1) enhancer, A03, that increases the levels of the neuroprotective enzyme SirT1 while not affecting levels of neurotoxic ...

Maintenance of NAD+ Homeostasis in Skeletal Muscle during Aging and Exercise
Cells, 2022 Nicotinamide adenine dinucleotide (NAD) is a versatile chemical compound serving as a coenzyme in metabolic pathways and as a substrate to support the enzymatic functions of sirtuins (SIRTs), poly (ADP-ribose) polymerase-1 (PARP-1), and cyclic ADP ribose

Inverse association of circulating SIRT1 and adiposity. A study on underweight, normal weight, and obese patients [PDF]
, 2018 Context: Sirtuins (SIRTs) are NAD+-dependent deacetylases, cellular sensors to detect energy availability, and modulate metabolic processes. SIRT1, the most studied family member, influences a number of tissues including adipose tissue.

Assaying Chromatin Sirtuins [PDF]
, 2013 Most of the sirtuins' nuclear substrates identified so far are histones or other chromatin-associated proteins and, thus, it is of special relevance the development of good biochemical techniques to analyze the biology of these proteins in the context of chromatin.

Sirtuin 1: A Dilemma in Transplantation
Journal of Transplantation, 2020 Sirtuin 1, a member of sirtuin family of histone deacetylase enzymes, has been implicated in a variety of physiologic and pathologic events, including energy metabolism, cell survival, and age-related alterations.
